The closer we get to the year 2015, the louder
people lament that our world hardly resembles the one depicted in Back
to the Future II. Although it will be awhile before any of us coast
around in a flying Delorean, we've piped down our complaints, as a
young French artist named Nils Guadagnin has built an exact,
actually-hovering replica of Marty McFly's pink hoverboard.

Guadagnin began the project in 2008 for an exhibition titled -- drum
roll -- "Back to the Future." Electromagnets allow the board to
levitate, while a laser system stabilizes it mid-hover. Although you
can't actually ride the board, it does hold up remarkably well when
poked and prodded. Check out the video below to see Guadagnin
demonstrate:
